I had this on my to-do list already, but I appreciate the suggestion. Now, the good news is: it's not the kernel, as the same thing happens with the kernel I was running previously: 2.6.37.5. The bad news: it still happens, and I think I know the culprit. mdadm was upgraded along with my kernel upgrade. So occam's razor suggests the new version of mdadm itself is to blame for the segfault. Unfortunately, while I diligently keep old versions of my kernel package, I don't have the previous version of mdadm lying around to investigate this further. Any suggestions? Cheers, Norbert
